i started this blog because i have a few projects i'm working on and wanted to bounce some ideas around.......

when i originally set this blog up, i couldn't find a link for posting blog entries, now i've found out how, so here goes......

1) working on a white paper about audio power amp output impedance and feedback.

2) working on a device that directly measures AC impedance the same way a DMM measures DC resistance, and does frequency sweeps and impedance graphs (and a whole lot more...). this device is a spin-off of the first project. this is the prototype and is a completely analog instrument.

3)working on a DSP based version of the impedance meter, using the DSP chip to act as the waveform generator, as well as compute the results of various tests.

a couple of projects using DSP for Software Defined Radio.

people who have read my posts will see that i use LTSpice for part of my prototyping process,...
